I went through two months of this. Sometimes weeks would go by with no problem, then alll of sudden, the boat takes a sudden turn as the compass heading changes for no reason.
to the fluxgate
compass numerous times, as the problem seemed intermittent.
Many times the boat would be fine, but if it took one big roll for any reason, all of a sudden the compass was totally off, sometimes by 100 degrees.
In times of desperation, I would try to run it that way, but sooner or later, the boat would make a sudden turn as the compass heading changed abruptly.
I did look for those proverbial cans of soup; many times.
I spent hours turning in circles trying to recalibrate it. Sometimes it worked, other times not.
I did't spend $thousands$ to fix it, only because i didn't have the $$ to spend.
Finally, after one really annoying morning spent going in circles, I went down to the cabin
to check the connections again and i realized just on the other side of the cabinet was a little battery powered LED, so I moved that and as I did, my hand touched the end of the cell phone
charge cord dangling off the night stand, probably inches form the compass
I knew then and there that was it, as the light was always there, but the cord many times would be on the night stand, and then in some seas would fall off to dangle right by the compass.
It's worked great since I unplug the charger
now when not is use.
Look for every
simple solution you can befor you do anything major.
